How to rotate a PDF and keep it that way
- Open the fileDrop one or more PDF files on the box, or click it to choose them.
- Turn the pagesClick the small arrows under a page, or select pages and use Turn left, Turn right or Upside down.
- DownloadThe new file opens the right way up in every reader. Your old file stays as it was.
With no page selected, the big buttons turn every page. Select a few pages first and they turn only those. Odd and Even are handy for a scan where every second page came out upside down: click Even, then Upside down.
Turning the view is not turning the file
Most readers have a rotate button. In Adobe Acrobat Reader, Chrome and Edge that button turns only what you see. Close the file and open it again, and the page is sideways once more. Send it to someone and it is sideways for them too. The reader never wrote the turn into the file.
This page writes it. Each page in a PDF carries a number that tells readers how to turn it before showing it. The tool changes that number and saves a new file. Nothing else on the page is touched, so text stays sharp and searchable.
What a PDF stores: the Rotate entry
Inside the file, a page is a small dictionary of entries. One of them is /Rotate. Its value must be a multiple of 90, so a page can only be turned by 90, 180 or 270 degrees. There is no 45 degree page. When the entry is missing, the value is 0. Pick a turn below to see what the tool writes and how a reader shows the page.
<< /Type /Page /MediaBox [0 0 595 842] /Rotate 0 /Contents 12 0 R >>
0: the page shows as it was made.
The turn is clockwise. A value of 90 shows the top of the page on the right. Because the number is stored once per page, a 300 page file turns as fast as a one page file. The content stream with the text and pictures is not rewritten.
Scanned pages and automatic orientation
A scanner saves the page the way the paper went in. Feed a stack sideways and every page comes out sideways. Some scanner apps read the text to guess which way is up. This page does not do that. It turns only the pages you pick, and it never guesses. For a sideways stack, click All and turn once. For a stack where only the back sides are wrong, use Odd or Even.
Thumbnails show the turn right away, so you can check the whole file before you download. A page you turned has its angle written in the corner.
How other apps rotate a PDF

| Preview on a Mac | Tools, then Rotate Left or Rotate Right, then save | Yes |
| Chrome and Edge | The rotate button in the viewer | No. Downloading gives the old file. |

More PDF tools
To put several files together, use merge PDF files. It can turn pages too. To send only some pages, use split a PDF. For text, signatures and deleting pages, open the PDF editor. The format itself is described on Wikipedia, and the file is written by pdf-lib, an open source library that runs in your browser.
